GLASSWORKING- APPARATUS.

Application ed .Tune 3U, 1921.

To @ZZ whom it may concern Be it known that l, donn 1. lvlrnLrnnN, a

citizen of the United States, residing` in Bayonne, county of Hudson, State of New Jersey, have invented certain new and useful llnproven'ients in (ilassworlring Apparatus, of which the :following is a specification.

' My invention relates to apparatus for performing operations upon glass or glass ware, and especially for cutting or ornamenting glassware, such as drinkingl glasses, tumblers and the like.

My invention resides in features of structure and combination hereinafter described and claimed.

For an illustration of one of various forms my apparatus may taire, reference is to be had to the accon'ipanying drawings, in which:

Referring` to Figs. 1, 2 and 8, T is a sta tionary member or table having legs or sup- Serial No. 481,501.

ports 1 by which it is supported upon a subbase or frame 2. Secured to or integral with the member 8 is the vertical cylindrical bearing member 4, upon which is rotatable the vertical sleeve 5 carrying at its upper end the rotatable member or table or platform R driven by the gear 6 secured upon the sleeve 5 and in turn driven by the worm or pinion 7 secured upon the shaft 8 driven by the sprocket wheel 9 driven by a sprocket chain 10 driven by a sprocket wheel 11 upon the shaft 12 carrying the pulley 13 driven by belt 14 from the electric or other motor M. Upon the shaft 12, which preferably rotates slower than the shaft 8, particularly when the latter drives a worm 7 for driving the gear 6, is secured a bevel gear 15 driving' the bevel gear 16 secured upon the shaft 17 extending through the bearing member 4- and secured at its upper end to the bevel gear 18 driving the series of bevel pinions 19 secured upon Ishafts having hori Zontal bearings in the bearing ring 20secured upon and rotating with the rotary table l?. Each pinion 19 drives a shaft 21 through a universal coupling 22. Each shaft 21 drives a shaft 28, Fig. 4, through a universal joint 24.

Referring to Figs. 4 to 9 inclusive, the shaft drives a shaft 25, the driving sleeve 26 permitting adjustment of the shafts 28 or toward or away from each other when suitable or desirable to move the cutters or cutting wheels, hereinafter described, toward or away from each other.

.,ecured upon the table R are the slides 27, by which are held the vertical standards 28 carrying the horizontal pivot shafts 29 upon which are pivoted the cylindrical members 8O having the upwardly extending standards or arms 81 carrying at their upper ends the sleeve members 82, between which are held and capable of vertical adjustment the sleeves 88, within which are disposed the bearings 84 for a rotary shaft 85, upon whose upper end is secured the cutter or grinding wheel 86. The shaft is driven through the sleeve 87, which is longitudinally adjustable `with respect to the shaft 85, the' sleeve 37 being driven bythe shaft 8S, in turn driven through the universal joint 89, driven by the gear 40, in turn driven by the gear 41, the gears 41 being secured, respectively, upon the shafts 23 and 25.

Secured to or integral with each member 30 is a laterally extending arm 42 carrying at its end an adjusting screw 43 bearing upon the upper end of the membery 44 slidable vertically in the member 45V secured upon the table R. Vertically slidable in the inember 45 is the plunger or cam follower 46 in whose lower end is pivoted aroller 47 engaging the cams 48 disposed in a circumferential series upon the stationary table T,` as indicated in Fig. 3. An adJustable screw 49 threaded in the member 44 abuts against the upper'end of the member 46, adjustment of the screw 49 serving to adpist the vertical throw of the member 44 by the cam 48.

Disposed between the two cutter structures of apair carried by member 7 6 and vertically adjustable therewith with respect to the table R is a bracket 50 carrying a sleeve 51.

Referring to Figs. 12 to 15 inclusive, there isy disposed within the sleeve 51 the sleeve or`bushing 52, upon the upper end of which is' secured'the body 53 of a chuck or holder for the glass article Gr which, in the example illustrated, is a tumbler or drinking glass blank'having formed integral therewith the extension or neck 54 having at 55 a bead or equivalent formation and trul i concentric with the axis of the article which with its extension 54 is preferably formed in a mold, whereby the shoulder 56 and the bead 55 are truly concentric with the'body or tumbler proper. Within the chuck body 53 is longitudinally movable the member 57 secured upon the rod 58, to whichy is secured the collar 59, between which and the abutment 60 within the sleeve 32 is disposed the helical spring 61, which normally thrusts downwardly upon the collar 59 toA move the member 57 to the position indicated in Fig. 12, upward movement ofthe rod 58 moving the member 57 upwardly to the position indicated in Fig. 13. Pivoted upon' the member 57 at a plurality of'circumferentially spaced points are the fingers 62 pivoted at 63 and havingv the shoulder 64 adapted to engage the aforesaid bead or shoulder 55 upon the extension 54 of the article G. Each finger 62 has a lug`65 adapted to engage with the upper inclined edgeofthe body member 53 for movement therealong axially of the article G. Each finger 62 also has a lug or bearing point 68 for slidingly engaging the interior surface vof the body member As indicated in Fig. 12, the extension 54 of the article Gr preferably has formed thereon a conical surface adapted to engage the ,conical surface 66 of the cup member 67.

With the parts in the position indicated in Fig. 1 2, the article G is firmly held with its axis co-incident with the axis of the sleeve 52, which is rotatable within the sleeve 51'by the notched wheel or indexing wheel 69. When the rod 58 is forced up wardly in opposition to spring 61 by member 70, hereinafter described, the member 57 is moved upwardly, thereby tilting thc` fingers 32 to the position shown in Fig. 13, freeing the bead or shoulder 55 therefrom and allowing removal of the article with its attached extension 54. Upon removing the article G, the springs 71 move the cup member 67 upwardly with respect to Incinber 57. Upon inserting another article G, it is pressed downwardly, its conical shoulder engaging the conical surface 66 of the member 67, pushing it downwardly in opposition to springs 71, this movement also forcing the member 57 downwardly in opposition to spring 61 and causing the upper ends of the fingers 62 to move inwardly and engage by their shoulder 64 upon the bead or shoulder 55 of the extension 54, thus holding the article in the position indicated in Fig. 12.

In the examples illustrated, but to which my claims shall not be limited except where so expressly stated, the article G has the extension 54 formed thereon in a mold or otherwise, as described in my co-pending application Ser. No. 459,651, the blowing being accomplished through the lower end of the neck or extenscion 54, as at the hole 72, where the blow-pipe is attached during the blowing or molding operation. 'Y

It will be understood. however, that my present invention contemplates also holding a glass article, as a tumbler, by any other suitable means than that herein described. as for example, a chuck structure entering the tumbler itself and expanded therein, the tumbler or other article in such case being free of the extension 54 or the like. i

The member' 76 is upon the end of a bifnrcated lever 74 (Figs. 4 to 9 inclusive). pivoted at 73 and having a lug 75. The pivots 73 are carried by the member 76 vertically adjustable in the member 45 secured upon the table R, the member 76 carrying also the bracket 50. Y Beneath the lug 75 is disposed in the sleeve 77 carried by the table R the vertically movable plunger or cam follower 78 carrying at its lower end a roller 79 adapted to be engaged and actuated by the cam 80 on the stationary table T, Fig. 3, the roller 79 rolling up upon the cam 8() once per revolution of the table R, moving the plunger 78 upwardly, and thereby actuating the lever 74, which in turn moves the rod 58 upwardly to actuate thc chuck to free thc article (l, which is removed and replaced by another` the holder or chu/'k gripping the article as the roller 79 again passes off of the cam 80.

Pivoted to the member 51 at 81 isa bell crank lever having the arms 82 and 83. Co- ;.cting with the arm 83 is the plunger or cam follower 84 movable vertically in the loo lill

lll

sleeve 85 carried by the table lt. The plunger 84: carries at its lower end a roller 8G adapted to ride upon the cams 87 disposed in a circumferential series upon the stationary table T, Fig. 3. Vhen the roller S6 rolls up upon a cam 87, the plunger 8a is raised, thereby rotating the bell crank lever upon its pivot 81 and causing the pawl 8S resiliently mounted in the lower end of the bell crank arm 82 to step the aforesaid :notched or indexing,l wheel b9 around one notch. The wheel G9 is loclred after each actuation in the position to which actuated by a pin or dog 89, Figs. G, 7 and 8, suitably mounted and biased by spring or equiv` alent means to the locking position,

Referring to Figs. l, 'lO and il, there is secured upon the upper end of each sleeve 33 a plate 90 having the arcuate upstandinn; member 91 surrounding the cutter wheel 36 as a guard or shield. Secured to and extending` radially outward from the member 91 is a threaded rod 92 extending; through a slot or hole in the upstanding lut;1 upon the member 9d, a sprin 95 surrounding the rod 92 and disposed between the lug; 93 and the member 9i. Threaded upon the red 92 is the thumb mit 96, which whenturned causes radial movement of the member 9a to suitably adjust or position the stop 97 carried at the end of the member 9i'and embracing the edge of the plate 90, the stop 97 serv-- ing to limit the movement of the cutter Wheel 36 into or toward the article Gr, such movement of the cutter wheel 36 toward the article (Jl being arrested when the stop 97 engages the article Gr.

The operation is as follows: i

With the motor M in operation and the shafts 8 and 1E?l rotated thereby at suitable speeds, the worm 7 rotates the gear 6, which in turn rotates the table lt carrying the numerous groups of cutter mechanisms disposed circumferentially thereof, as indicated in dotted lines, Fig'. l.; and simultane ously the bevel gear l5 drives the bevel gear 16, rotating the bevel gear i8 at suitable speed and thereby driving; the shafts 23 and 25 of each cutting unit. The cutters 36 of each unit are so rotated at desired speeds, cutting into the article G froni`opposite sides thereof and making cuts therein, in the example illustrated at different angles, due to the inclination of the of the article (l. is the cutters rotate and cut into the glass, their supports 32, 32 are pulled toward each other by the spring 98, F 2, the depth of cut being limited by the aforesaid stops 97, unless the cut-ters 36 are removed from the article G prior to reaching1 such depth. The table lt is continuously rotating, and the wheels` 3G cut the article Gr until the plunger or cam follower 4:6 is raised by the roller 47 rolling up to sufficient height upon a cam 48, whereupon the levers t2 are rotated, niovinp; the supporting; structure of the cutters away from the article Gf.

lllhile the cutters are so out of engageA ment with the article, the plunger or cam 7U follower @il is raised b y lthe roller 86 rolling up upon a cam 87, 3 and 7, thereby raising),I the cam follower 9dwhioh aetuates the index wheel 69, thereby rotating the ticle Gr through suitable angle, and thereafterthe cutters 36 again more toward each other and engage the article (i as the folA lower lo again descends as allowed by the cam d8. rlhis operation continues, the cutter wheels 86 periodically engaging and departing from the article G, which latter is periodically stepped around until the design is cut completely around the circumference of the article, which occurs by the time the cam follower 7 8 co-aets with the cam 80, when the roller 79 rolls up upon the cain 80, actuating the rod to open the holder or chuck, releasin" the article Gr, which is then removed by the attendant or operator, and an uncut artigcle placed in the chuck, which then grasps the article as the roller 79 passes olf of the cam 80.

The foregoingI is the cycle of operation for each cutting unit, and as each cutting' unit comes to position corresponding with the cam 90, the cutting1 of the article completed, and the attendant removes it and replaces it with another to be cut.

its the cutters 36 wear or decrease in diameter, they may be adjusted towards each 100 other by rotatingn the adjusting screws 9 Figs. 5, (i and 7, whereby the right and left hand threads on the member 99 engaging in blocks 100 on the standards 29 more those standards, and therefore the cutters carrier thereby, toward and away from each other. This adjustment may be utilized also for accommodating articles G of different die ameters, or for any other purpose.

lfor adjusting the cutt rs ,fertically to suitable positions longitruliually of the article Gf, the sleeves 3B are adjusted in their holders 32 and the couiriling between shafts and 99 is correspondingly adjusted. 11u
